摘要： 在采用影响函数法分析四辊轧机轧辊弹性变形的基础上,以某1 250 mm热带轧机为对象,研究了四辊热带轧机支撑辊辊型曲线各种影响因素对辊间压力及带钢出口凸度的影响规律,为支撑辊辊型曲线优化设计提供了重要的理论依据.研究结果表明:倒角长度、倒角高度、倒角类型以及辊身凸度均对辊间压力分布和带钢出口凸度具有较大的影响,在进行辊型曲线优化设计时应根据现场实际选择合适曲线类型和参数范围,同时保证轧机的凸度控制能力满足生产要求.

Abstract: The impact of influencing factors of backup roll profile, a curve surface, on the distribution of rolling pressure and the strip crown at exit of a 1250 mm hot strip mill was investigated, based on the influence function method to analyze the elastic deformation of rolls on a 4-high hot strip mill. The aim is to lay an important foundation theoretically for the optimum design of backup roll profile. The results showed that the length, height and type of roll chamfers and roll crown have great influence on the distribution of rolling pressure and the strip crown at exit. It's important to select suitable rolls' curve surfaces and relevant parameters in accordance to the actuality in site during the optimum design of backup roll profile, with the crown controllability of the mill ensured to meet the productive requirements.
